Unionid mussels were collected by quadrat sampling at three mussel beds in Reach is of the Upper Mississippi River (UMR) between July 1994 and September 1995. A total of 7,107 unionids were collected representing 26 species, including the federally endangered Lampsilis higginsi, state endangered Plethohosus cyphyus and Cumberlandia monodonta, and state threatened Ellipsaria lineolata. Mean densities at our study sites ranged from 53,4 to 118.3 mussels/m2. Comparisons with data collected at...

The objective of this thesis is to investigate the use of the Universal Controller to control the DC-to-DC power converter and the Auxiliary Resonant Commutated Pole (ARCP) power inverter. These power electronic devices are central to the development of a DC Zonal Electric Distribution System (DC ZEDS) that is scheduled for application in the twenty-first century surface combatant (SC-21). The development of appropriate closed-loop controls is a key element to this design process. The Universal...
